在此，我们提出了一种新型的再生式光纤传感器，用于地热水中碳酸钙结垢的形成。该传感器是用铂网覆盖无包层的多模光纤芯制成的。该传感器可以根据水在阳极电解过程中pH值的变化，将沉淀在光纤表面的水垢溶解，从而实现多次测量的再生。该传感器已成功应用于日本松城天然地热水中的水垢形成监测。
Herein, we present a novel regenerative fiber optic sensor for calcium carbonate scale formation in geothermal water. The proposed sensor was fabricated by covering an unclad multimode fiber core with a platinum mesh. This sensor can be regenerated for multiple measurements by dissolving the scale precipitated on the fiber optic surface based on the changes of pH accompanying the anodic electrolysis of water. The implementation of the proposed sensor was successfully applied to monitor the scale formation in natural geothermal water situated at Matsushiro, Japan.
